[0002] Cement mortar vibration tables are mainly used for compacting materials, reducing air and gaps within them. Often, cement mortar vibration tables are used to compact cement mortar into cement test blocks before testing the density of cement specimens. This facilitates testing of the cement mortar, thereby improving the quality of cement used in construction and contributing to refined construction and green building practices.

[0003] A high-stability cement mortar vibration table with publication number CN209764537U includes a base and a swing arm rotatably connected to the base. A platform is provided on the side of the swing arm away from its rotatable connection position. A cam mechanism for linkage and flipping of the platform is provided between the platform and the base. A test mold pressure plate is hinged to the platform. A fixed shaft is horizontally fixed to the free end of the test mold pressure plate. A fixing mechanism for fixing the fixed shaft is also provided on the platform. The high-stability cement mortar vibration table of the above invention has the feature of improving the stability of the test mold.

[0004] The above-mentioned existing technology has the following disadvantages: When using the cement mortar test mold 4 that matches this cement mortar vibration table, the test mold 4 needs to be disassembled into a base 28, an end plate 29 and a partition plate 30.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figure 1-7This invention provides a technical solution: a high-stability cement mortar vibration table with anti-splashing capability, comprising a base 1, a swing arm 2 rotatably connected to the base 1, a platform 3 on the side of the swing arm 2 away from its rotatable connection position, a test mold 4 on the top of the platform 3, a cam mechanism 5 for linkage of the platform 3 to flip the platform 3 between the platform 3 and the base 1, and a test mold pressure plate 6 for pressing the test mold 4 hinged on the platform 3. The test mold 4 includes two symmetrically arranged cement mortar mold easy-to-remove mold groups 7, which are fitted together. Each cement mortar mold easy-to-remove mold group 7 includes symmetrically arranged cement mortar mold cavities 8 and an easy-to-remove mechanism 9 disposed between the two cement mortar mold cavities 8. The inner wall of the side of the two cement mortar mold cavities 8 that is close to each other is a slidingly arranged demolding template 10. A driving area 11 is provided between the two demolding templates 10. The easy-to-remove mechanism 9 includes a base plate 91 and a driving mechanism 9. The rod 92 and worm gear 93 are fixed to the center of the two demolding templates 10. The middle part of the drive rod 92 is rotatably mounted on the base plate 91 and its two ends are respectively connected to the demolding templates 10 on both sides. The drive rod 92 is threadedly connected to the demolding templates 10 and can drive the two demolding templates 10 to move towards each other. The worm gear 93 is rotatably mounted on the base plate 91. The junction of the worm gear 93 and the drive rod 92 forms a meshing connection of the worm gear 93. A push plate 12 is provided on the side of the two cement mortar mold cavities 8 that is far away from each other. A connecting plate 13 is connected between the demolding template 10 and the push plate 12. The connecting plate 13 is slidably mounted outside the cement mortar mold cavity 8 and drives the push plate 12 to slide. It should be noted that when the cement slurry is poured into the cement mortar mold cavity 8, grease can be applied to the demolding template 10. After the demolding template 10 moves, it helps the cement mortar module to separate from the demolding template 10 first.

[0028] Specifically, a sealing plate 14 for closing the drive area 11 is fixed on the top of the two detachable templates 10 on the cement mortar mold assembly 7. The worm gear 93 passes through the sealing plate 14 and extends upward. A rotating rod 15 is provided at one end of the worm gear 93 outside the sealing plate 14. The worm gear 93 can be easily rotated by the rotating rod 15 outside the sealing plate 14.

[0029] Specifically, slides 16 are symmetrically arranged on both sides of the drive area 11, and the two sides of the demolding template 10 extend into the slides 16. When the cement mortar mold cavity 8 is manufacturing cement mortar modules, the demolding template 10 is located on the side of the slide 16 closest to the cement mortar mold cavity 8 to prevent cement slurry from leaking into the slide 16.

[0030] Specifically, the connecting plate 13 consists of a straight plate 131 and a horizontal plate 132 connected to the end of the straight plate 131 away from the demolding template 10. The straight plate 131 passes through the cement mortar mold assembly 7 and extends to the side of the push plate 12 away from the demolding template 10. The horizontal plate 132 is provided with a push rod 17 connected to the push plate 12 on the end face near the push plate 12. A sliding space is formed between the push rod 17 and the push plate 12.

[0031] Specifically, the push plate 12 is provided with a base sleeve 18 on the side near the horizontal plate 132, and a limiting groove 19 is provided on the side of the base sleeve 18 near the push rod 17. A limiting plate 20 is provided at the end of the push rod 17 that is inserted into the limiting groove 19. The limiting plate 20 is slidably disposed in the limiting groove 19. In this way, after the demolding movement and separation from the cement mortar module, the limiting plate 20 at one end of the push rod 17 will slide to the end of the limiting groove 19 and start to push the push plate 12, thereby causing the cement mortar module to separate from the inner wall of the cement mortar mold cavity 8.

[0032] Specifically, the cement mortar mold cavity 8 is provided with a plate groove 21 for the push plate 12 to be embedded, and the cement mortar mold assembly 7 is provided with a sliding groove 22 for the horizontal plate 132 to slide, and the sliding groove 22 is connected to the plate groove 21.

[0033] Specifically, a second limiting groove 23 is provided at one end of the two demolding templates 10 that are close to each other. A second limiting plate 24 is provided at one end of the drive rod 92 that is inserted into the second limiting groove 23. The second limiting plate 24 is threaded into the second limiting groove 23. In this way, the sliding distance of the demolding templates 10 can be limited. This method can be used as a reference when manufacturing cement mortar modules in the cement mortar mold cavity 8. Figure 4 The cement mortar mold assembly 7 is in a disassembly state. When removing the cement mortar module from the cement mortar mold cavity 8, refer to [the relevant documentation / reference]. Figure 6 The cement mortar mold is in state 7, which is easy to disassemble.

[0034] Specifically, a top plate 25 is embedded at the bottom of the cement mortar mold cavity 8. The top end face of the top plate 25 is flush with the inner wall of the bottom of the cement mortar mold cavity 8. The cement mortar mold easy-to-remove module 7 is located at the bottom of the cement mortar mold cavity 8 and has a hidden opening. A compression spring 26 is installed in the hidden opening. The top of the compression spring 26 abuts against the top plate 25. The cement mortar mold easy-to-remove module 7 is provided with a fixing member to fix the end of the top plate 25 away from the demolding template 10. The other end of the top plate 25, which is fixed by the fixing member, is located at the lower end of the demolding template 10 and abuts against the demolding template 10. In this way, the cement mortar module can be easily pushed out of the cement mortar mold cavity 8 and is easy to remove.

[0035] Specifically, the fastener is bolt 27, which is inserted into the cement mortar mold to remove the mold assembly 7 and insert into the side wall of the top plate 25.

[0036] A specific application example of this embodiment is as follows:

[0037] When using this device, apply grease to the end face of the demolding template 10 located on one side of the cement mortar mold cavity 8, then pour cement mortar into the cement mortar mold cavity 8 (the pouring method is the same as the existing method), and then place the test mold 4 on the test mold pressure plate 6 and lock it in place (the fixing method is the existing method, so it will not be described in detail). The cement mortar inside the test mold 4 is compacted by activating the cam mechanism 5. The test mold 4 is then removed from the platform 3. By rotating the rotating rod 15, the rotating rod 15 drives the worm gear 93 to rotate, and the worm gear 93 drives the drive rod 92 to rotate. Under the threaded connection between the second limiting plate 24 and the second limiting groove 23, the rotation of the drive rod 92 will drive the two demolding templates 1... Slide the formwork 10 towards the side that is closer to each other. The sliding of the formwork 10 will cause the connecting plate 13 to slide. The sliding of the connecting plate 13 will cause the limiting plate 20 to slide a certain distance within the limiting groove 19. Under the action of the applied grease, the formwork 10 will first detach from the cement mortar module. Continue to rotate the rotating rod 15, and the formwork 10 will continue to slide. At this time, the limiting plate 20 will abut against the inner wall of the limiting groove 19, thereby pushing the push plate 12 to slide out of the plate groove 21, thereby causing the cement mortar module to detach from one side of the inner wall of the cement mortar mold cavity 8. Continue to rotate the rotating rod 15 to drive the formwork 10 to move until the second limiting plate 24 moves to the inner end of the second limiting groove 23 to fit (refer to...). Figure 6 At this point, the top plate 25 will be completely inside the cement mortar mold cavity 8 and will not be pressed down by the demolding template 10. Loosen the bolts 27 on the outside of the cement mortar mold assembly 7 to release the bolts 27 from the top plate 25. Under the action of the compression spring 26, the top plate 25 will push the cement mortar module upward, making it easy for the operator to remove the cement mortar module. After the cement mortar module is removed, when the next grouting is needed to make cement mortar modules, simply press the top plate 25 into the hidden opening and lock it with the bolts 27. At the same time, reverse the rotating rod 15 to drive the demolding template 10 to move to the initial position (refer to...). Figure 4 ).
